Hybrid tea rose plant named `Macoborn`

ABSTRACT

A hybrid tea rose plant variety producing flowers of multiple shades or tones of pink.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct hybrid tea rose variety which was originated by my crossing the variety known as `Louise Gardner` as seed and the variety known as `West Coast` as pollen parent. The varietal denomination of this new rose is `Macoborn`.

SUMMARY OF THE INVENTION

Among the novel characteristics possessed by this new variety which distinguish it from its parents and all other varieties of which I am aware are its attractive bright colored flowers with slightly scalloped petals borne on a free flowering plant.

Asexual reproduction by budding of the new variety as performed in Watsonville, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations. Other known forms of asexual reproduction may be also employed to asexually reproduce the new variety.

COMPARISON WITH PARENTS

`Macoborn` flowers are of multiple pink shades or tones whereas `Louise Gardner` flowers are a yellow red blend and `West Coast` flowers are pink and the plant has more profuse foliage.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration shows a typical flower of the new variety depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.
